I use greased lightning as well. Really good stuff. I've never used as they say though as I always wash car first then apply. It's so easy to apply and rub off. Have you ever been brave enough to try it without washing first?

I will probably get slaughtered for this but here goes.
Greased lightling will not last very long and will be okay if you didnt have a lot of time on your hands, otherwise you are better to polish and then use a separate wax, i usually only polish and wax twice a year on all my cars. Ford Mazda & BMW

I use super resin polish followed by gloss protection a few times a year and inbetween every month or so use the greased lightning. Have ordered some hd wax though as plan on claying it very soon ready for the summer. 😃☀

Froggy72 if you are planing to clay your car i would recommend the Bilt Hammer range as its reasonably priced easier to use that most clays and you can use water as a lubricant or i use water and a v small amount of car shampoo in a spray bottle.

The best "off the shelf" polish is easily AutoGlym SRP. It's been improved for 2012 and is less dusty than the old one. But remember a polish will NOT protect the car. You will need a top coat of wax for the protection.

Yeah I've got the wax sorted for the car. I just mainly needed the polish to prepare the surface and remove some of the light swirl marks. Also gives it the "showroom" finish before putting the wax on to protect the paint
